First
of all, let me explain what a "Fixed/Detachable" restoration is:
It
is a restoration that is held in place by screws. The patient cannot
remove it, but the dentist can. It's advantage is in that it acts like
a "permanent" restoration and is not removed unless it needs repair.
It is much harder to keep clean and service than removable restorations.
Implant supported
fixed restoration for edentulous lower arch. This is the classical Brånemark
restoration that was introduced in the early 1980's. It provides a functional
equivalent for missing teeth. This type of restoration is only used in
the completely edentulous patient.
Implant supported
fixed restoration for edentulous upper and lower arch. This is an example
of the same type of Brånemark restoration used in both the upper
and lower jaws.
Implant supported
fixed restoration for edentulous upper and lower arch. another example
of a completed patient treatment using a mandibular (lower) fixed/detachable
restoration and a maxillary (upper) bar overdenture.
Sometimes a great deal of hardware is necessary in order to get a fixed/detachable
restoration. This module deals with what is referred to as a fixed/detachable/superstructure
restoation.
Here is a patient
that I treated about 10 years ago. When I initially treated the case,
one
of the implants fractured during insertion. This shows how I handled
the situation.
